I was sitting with a 5th and 6th grader, and the 6th grader was working with the BBC's Mummy Maker at Discovery Kids - http://kids.discovery.com/fansites/tutenstein/mummymaker/mummymaker.html . He commented about using a hook to stir up the brains, and the 5th grader was hooked as well. The next step was to remove vital organs. The instructions said that one must remain to help the person reach the afterlife. A clue revealed that the conscience lived in that organ. The boys expressed their thoughts in conversation. The 5th grader said he thought it was the heart because it is the source of feelings about right and wrong. The 6th grader added that it might be the stomach because of the feeling you get in your stomach when you do something wrong. He opted to try the stomach and discovered heart was the correct answer. I was again reminded of the importance of letting students learn by sharing thoughts with peers.
